Abstract

para proporcionar uma estrutura de vedação com um amortecedor torcional e uma vedação de óleo que pode reduzir exposição a uma aba de vedação da vedação de óleo à matéria estranha que penetra a partir do entorno do amortecedor torcional. uma estrutura de vedação (1) com um amortecedor torcional e uma vedação de óleo inclui uma polia de amortecedor (10) servindo como um amortecedor torcional e uma vedação de óleo (20). a polia de amortecedor (10) tem um receptáculo de cubo anular (30) que é rebaixado na direção do lado externo e se estende na direção circunferencial ao longo de uma parte de ressalto (14) de um cubo (11). a vedação de óleo (20) inclui uma aba lateral (29) que se estende em direção ao lado externo. uma superfície circunferencial externa (31) do receptáculo de cubo (30) aumenta em diâmetro em direção ao lado externo, a aba lateral (29) da vedação de óleo (20) não entra no receptáculo de cubo (30), e uma folga anular (g1) é formada entre uma extremidade lateral externa (29a) da aba lateral (29) e uma extremidade lateral interna (31a) da superfície circunferencial externa (31) do receptáculo de cubo (30).to provide a sealing structure with a torsional damper and an oil seal that can reduce exposure to an oil seal sealing flap to foreign matter that penetrates from around the torsion damper. a sealing structure (1) with a torsional damper and an oil seal includes a damper pulley (10) serving as a torsional damper and an oil seal (20). the damper pulley (10) has an annular hub receptacle (30) which is lowered towards the outside and extends in the circumferential direction along a shoulder portion (14) of a hub (11). the oil seal (20) includes a side flap (29) that extends towards the outside. an outer circumferential surface (31) of the hub receptacle (30) increases in diameter towards the outside, the side flap (29) of the oil seal (20) does not enter the hub receptacle (30), and an annular clearance (g1) is formed between an outer side end (29a) of the side flap (29) and an inner side end (31a) of the outer circumferential surface (31) of the hub receptacle (30).
